Application filed @ctober 6, 1919.` Serial No. 328,552.

T0 all whom t may concern.'

Be it known that l, CesrAoNoLA OLIVER, of Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulimprovements in Pedimeters, of which the following s a full and cleardescription.

My invention relates to the art of providing proper shoes for deformedfeet.

As is well known, a deformed human foot is not only very irregular inshape, but its position with respect to the ground when walking iscommonly such that the stresses are not distributed so as to be withinthe comfortable limits. Moreover, the abnormal position of the footoften throws undue stresses on portions of the shoe when the person iswalking, thus distorting the shoe .and causingdiscomfort as well ascausing undue wear of the shoe.

llt is the principal object of my invention to provide means wherebymeasurements of deformed feet may be made in walking position which willenable a skilful Shoemaker to construct a proper shoe for the personsfrom whose feet the measurements were made.

rlFhe novel features of my invention are pointed out with particularityin the appended claims. The invention itself, however, together withfurther objects and advantages, will best be understood from thefollowing` description taken in connection with the accompanying drawingin which- Figure 1 is a perspective view of a device according to' myinvention. r Fig. 2 is a section taken on the line 2-2 of Fig. 1.

llfig. 3 is a plan view of a part of the apparatus shown in Figs. 1 and2 illustrating a drawing of a deformed foot such as would be made fromdata obtained by operating my apparatus for the use of the last-maker.

Referring to the drawing more in detail, 1 is a framework in which amirror 2 is supported by a suitable plate 3, the framework beingpreferably horizontal and therefleeting surface of the mirror beingexposed from above when the apparatus is in use. Mounted on the frameabove mirror 2 and spaced therefrom is a bar such as 4 which extendsparallel to the surface of the mirror. Bar 4 has graduated scale members5 and 6 fixed to its top and bottom surfaces, although the top andbottom surfaces of the bar may have the graduations placed.-direxploring lever 19.

,which is designed to eXtend 'toward the foot, yis formed with anupturned tip rectly thereon if desired. The bar 4 has a number ofappliances associated therewith whereby the desired measurements may beobtained. rlhese appliances comprise a vertical standard such as 7 whichis slotted as at 8 to permit the ready adjustment of the heel rest 9 ina vertical direction. A carrier 10 for the tape 1()LL is also adjustablymounted in the slot 8. Standard 7 is graduated at the side of slot 8 asshown at 8a, so that the height of the rest 9 on the standard 7 abovebar 4 can be easily noted. Slidably mounted on bar 4 are plates such as11 to which/are fastened a horizontal cross-bar 12 and a block 13. Atthe ends of bar 12 are upright standards such as 14 on which arevertically adjustable blocks such as 15 in which are mountedhorizontally adjustable graduated scale or caliper members, such as 16,at the ends of-which are fastened tapes such as 16a. Near the ends ofmembers 16 are mounted vertica ly adiustable graduated.

caliper members such as 16". ln blockl is a horizontally adjustable bar17 at one end of which is a post 18 mounted to turn on its centralvertical axis and at the upper end of post 18 is a horizontal shaft onwhich is pivoted a caliper member in the form of an rllhe end of lever19,

20 for use in determining the position and form of protuberances on thebottom of the foot. The other end of lever 19 is shaped as a pointer andcooperates with a vertical scale on a plate 217 indicatingthe height oftip 20, the `plate 21 being fixed to post 18. The bar 4 also carries ahorizontally adiustable block 22 on which is a vertical standard 23having1 a vertical slot 24 therein, the standard 23 being graduatedalong the edge of slot 24 ,as shown at 25 (Fig. 2). Adjustably mountedin the slot 24 is a toe rest 26 and Valso a graduated caliper member 27.Y

`Parallel to the bar 4 on the framework is a bar 4. At the end of bar 4is a standard 7 carrying a heel rest 9. lt will be understood that thebar 4 and standard 7 are providedk with the tape holder. side calipermembers, toe rest. and end caliper member,

all as described in connection with bar 4, J,but that these parts areomitted from the drawing for convenience of illustration.

In the operation of my device, bar 4 and its adjuncts are used: forobtaining measurements of the left foot; and bar e and its adjuncts,those of the right toot. The center line oit' the toot is placed on thecenter line ol' the bar, such as l, and the heel rest, such as 9, or toerest, such as 26, adjusted so the foot is in the position taken when theperson is standing with weight on the foot in question. The outline oithe foot around its maximum perimeter is then obtained by the calipermembers such as 16", readings of the horizontal and vertical positionsof members 16b being taken for various positions of the block 13 on thebar 1. rl`he vertical and horizontal position of points on the centerline of the toot on its front surface are taken by caliper member 27.The points above the heel of the foot on the center line tliereotl arenot so important as those on the front face, and the position of suchpoints can be obtained by one of the members 16 by moving block 13 toits extreme position on bar e. The positions of blocks 13 and 22, andconsequently the position of the vertical parts carried thereby, areeasily read even when the footis on the bar a, owing to the reflectionof parts 13, 22, and the scale on the under side of bar 4t in mirror 2.The mirror also assists materially in discovering protuberances. These,when discovered, are explored and plotted in an obvious manner by aid ofmember 19, the end 2O of which can be brought against the protuberanceand its outline determined by rectilinear movements of parts 13 and 17,and swinging movements of part 19 on the vertical axis ot post 13, theangular position of part 19 on its horizontal axis being noted on thescale oirplate 21 and changed as found necessary in conjunction with thechanges in position of the bloclr 13 and bar 17. Cin cumerentialmeasurements are obtained by tapes, such as 10a and 16a, tape 10aLbeing' particularly convenient for obtaining the circumferentialmeasurements above the heel.

For convenience in platting the data obtained by the use of theapparatus above described, l prefer to combine therewith a square board28 having two parallel pins, such as 29, lined thereto, and projectingtherefrom near adjacent corners and ar ranged so that they may beinserted into clips such as 30 on the framework 1. The edges oi" board23 parallel to pins 29 carry clamping' bars such as 31 which areattached to board 28 by spring members such as 32, so that bars 31 maybe readily lifted enough to insert a sheet 33 to be drawn upon under thebars 31, such sheet will then be held firmly in place after it has beeninserted thereunder. Any convenient form of drawing instrument, such asthe square 34, may be used in transferring the data obtained by use .ofthe pedimeter to the drawing sheet. One edge of board 28 and theclamping members 31 are preferably graduated to facilitate the draftingoperations.
